DETROIT, MICHIGAN, .A CORPORATION OF 'DELAWARE i f v viiiv'rrtn'ronV Application ala March ao, 1929. serial No. 351,336.

This invention relates to a ventilator and more particularly to a ventilator for use in a vehicle body. ,Y Y y When ventilators are used in the side of an n automobile cowl, the means for operating the shutter of the ventilator usuallyconsists of a lever projecting into the body. When it is desired to open the ventilator the lever is pushed` by the foot and when the ventilator is closed the reverse movement is necessary. This has been found objectionable due tothe fact that the operator scufs his shoe when operating the lever for closingthe ventilator. It is, therefore, Y l invention to provide` a mechanism which opens and closes the ventilator by pushing on the operating lever.

Another object of the invention is to provide a tension means on the cover which holds the cover ,under tension in either opened or closed position.

A further object of the invention is to provide a ventilator having a frame, cover and joperating means assembled as a unit to be placed adjacent an opening in the vehicle ody.

Other objects and advantages of the invention will more fully appear from the followj jing description and claims taken in connec- 0 tion with the accompanying drawing,` in

which; A y,

Fig. l is a bottom view of the ventilator. Fig. V2 is a sectional view yon line 2 2 of 1 F ig.`1 showing thecover in closed position.

Fig. 3 is a View corresponding to Fig. 2, but

showing the cover in opened position. j

Referring to the drawing wherein I have illustrated one particular embodiment of my `invention, the reference numeral 10 designates a body panel such as the cowl of an automobile body and is provided with an opening 12, the periphery thereof being turned inwardly as at 14. The ventilator li-"unit, which is received on the inner face of the panel 10, consists of a rectangular frame work 16 of 4Z section7 a cover L18 pivotally supported on the Z section, and anoperating mechanism. v

On the inner surface ofthe'panel 10 the Ausual trimming 20 has been shown and the an important object 4of thisY opening 22l in thetriminner face of the panel frame 16 ts in an ming, engaging the 10. The Z frame 16 24 which rests against the inner `face of the trimming 20. The portion 26 of the Z frame closesthe periphery of the opening 22 and a face plate 28, provided with an opening 30, engages the panel 10. The face plate is provided with a recess portion 32 to receive the inwardly turned flange 14vand a flange 34 is provided with a flange extendsinto vthe opening 12. The flange 34 f forms a seat for the cover 18 when it is in closed position.

A pair of supporting brackets 36 are secured to the face plate 28 which Vsupport a rod 38. Pivotally supported on the rod 38 are two stampings 40, each having a rib 42 and a flange 44 which is secured to the cover 18, such as by spot welding. Secured to the portion 26 of the Z frame, opposite the bracketsv 36, is a U shaped stamping 46 which supports a rod 48. A cam 50 and a handle 52 are pivotally supported on the rod 48. Pivotally supported on the central portion of the U shaped member 46 I have provided a U shaped spring member 54 having its outer ends pivotally engaged in the rib 42. The U shaped member 54 is longer than the distance between its end supports and the arms of the memberA 54 are urged'inwardlys'oy that the ends of the spring are held under tension in the openings of the ribs '42. The cam `50 bears against both arms of the U shaped member at all times.

The adjacent 'ends of the cam 50 and han-v dle 52 are notched as shown at`56 and a coiled spring 58, urges the handle toward the cam 50 with the notches of the handle 52 engaging the notches of the cam 50. The opposite; 1

ends Vof the spring 58 are bent outwardly, one to engage an arm of the U shaped member 46, and the other to engagey the outwardly'ex-V tending portion of the handle urging the handle in one direction. j

When the cover is closed the low portion 52, thereby d of the cam 501is in engagement with the arms of the U shaped member 54 and when the operator pushes the handle in a direction as indicated by the arrow in Fig. 2, the notches of the handle, in engagement with the notches lower portion of the arms 54 urging the vframe having 'an' openingtherein, a cover cover outwardly as shown in Fig. 3. When the handle is released the spring 58 urges the handle back toits normal position leaving the cam 50 in a position as shown in Fig. 3. When lit is desired to close the cover the handle is again pushed in the direction of the arrow and the cam is rotated back -to theposition as shown in Fig.4 2, the tension of the spring closing .the cover'.

A gasket 60 is provided onV the under sur! face of the cover 18 to engage with the portion 34 of the Z shaped frame.

It will be understood that applicant has provideda ventilator which can be installed asy aun-it and that the operation of the device-is simple.- same movement operates toV either close or open the cover and that the handle returns to its normal position after the coverhas been opened orclosed.. The cover isheld in either anopenedA orV closed position by spring tension.v v

Various changes, including the size, shape and arrangement of parts, may be made with out departingfrom the spirit of my invention and itis not my 'intention to limitthe scope' ,thereof other than by the terms of the appended claims.
